This value is only used once inside amd_mp2_get_sensor_num(), so there is no need to store this in the amd_mp2_dev struct, amd_mp2_get_sensor_num() can simple use a local variable for this.

[ Upstream commit 25615e454a0ec198254f17d2ed79b607cb755d0e ]

Some BIOS-es do not initialize the activestatus bits of the AMD_P2C_MSG3 register. This cause the AMD_SFH driver to not register any sensors even though the laptops in question do have sensors.

Add a DMI quirk-table for specifying sensor-mask overrides based on DMI match, to make the sensors work OOTB on these laptop models.

[ Upstream commit 69d5ff3e9e51e23d5d81bf48480aa5671be67a71 ]

The driver registers an interrupt handler in _probe, but didn't configure them until later when the _open function is called. In between, the keypad can fire an IRQ due to touchpad activity, which the handler ignores. This causes the kernel to disable the interrupt, blocking the keypad from working.

Fix this by disabling interrupts before registering the handler. Additionally, disable them in _close, so that they're only enabled while open.

BEET mode replaces the IP(6) Headers with new IP(6) Headers when sending packets. However, when it's a fragment before the replacement, currently kernel keeps the fragment flag and replace the address field then encaps it with ESP. It would cause in RX side the fragments to get reassembled before decapping with ESP, which is incorrect.

In Xiumei's testing, these fragments went over an xfrm interface and got encapped with ESP in the device driver, and the traffic was broken.

I don't have a good way to fix it, but only to warn this out in dmesg.

In function displback_changed, has the call chain displback_connect(front_info)->xen_drm_drv_init(front_info). We can see that drm_info is assigned to front_info->drm_info and drm_info is freed in fail branch in xen_drm_drv_init().

Later displback_disconnect(front_info) is called and it calls xen_drm_drv_fini(front_info) cause a use after free by drm_info = front_info->drm_info statement.

My patch has done two things. First fixes the fail label which drm_info = kzalloc() failed and still free the drm_info. Second sets front_info->drm_info to NULL to avoid uaf.

After a short network outage, the dst_entry is timed out and put in DST_OBSOLETE_DEAD. We are in this code because arp reply comes from this neighbour after network recovers. There is a potential race condition that dst_entry is still in DST_OBSOLETE_DEAD. With that, another neighbour lookup causes more harm than good.

In best case all packets in arp_queue are lost. This is counterproductive to the original goal of finding a better path for those packets.

I observed a worst case with 4.x kernel where a dst_entry in DST_OBSOLETE_DEAD state is associated with loopback net_device. It leads to an ethernet header with all zero addresses. A packet with all zero source MAC address is quite deadly with mac80211, ath9k and 802.11 block ack. It fails ieee80211_find_sta_by_ifaddr in ath9k (xmit.c). Ath9k flushes tx queue (ath_tx_complete_aggr). BAW (block ack window) is not updated. BAW logic is damaged and ath9k transmission is disabled.

commit b166a20b07382b8bc1dcee2a448715c9c2c81b5b upstream.

If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock held and sp->do_auto_asconf is true, then an element is removed from the auto_asconf_splist without any proper locking.

This can happen in the following functions: 1. In sctp_accept, if sctp_sock_migrate fails. 2. In inet_create or inet6_create, if there is a bpf program attached to BPF_CGROUP_INET_SOCK_CREATE which denies creation of the sctp socket.

The bug is fixed by acquiring addr_wq_lock in sctp_destroy_sock instead of sctp_close.

This addresses CVE-2021-23133.

commit 8ca7cab82bda4eb0b8064befeeeaa38106cac637 upstream.

commit df7b59ba9245 ("dm verity: fix FEC for RS roots unaligned to block size") introduced the possibility for misaligned roots IO relative to the underlying device's logical block size. E.g. Android's default RS roots=2 results in dm_bufio->block_size=1024, which causes the following EIO if the logical block size of the device is 4096, given v->data_dev_block_bits=12:

E sd 0 : 0:0:0: [sda] tag#30 request not aligned to the logical block size E blk_update_request: I/O error, dev sda, sector 10368424 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0 E device-mapper: verity-fec: 254:8: FEC 9244672: parity read failed (block 18056): -5

Fix this by onlu using f->roots for dm_bufio blocksize IFF it is aligned to v->data_dev_block_bits.

commit bf52dc49ba0101f648b4c3ea26b812061406b0d4 upstream.

Don't zero out the watermarks for the Y plane since we've already computed them when computing the UV plane's watermarks (since the UV plane always appears before ethe Y plane when iterating through the planes).

This leads to allocating no DDB for the Y plane since .min_ddb_alloc also gets zeroed. And that of course leads to underruns when scanning out planar formats.

The entry from EL0 code checks the TFSRE0_EL1 register for any asynchronous tag check faults in user space and sets the TIF_MTE_ASYNC_FAULT flag. This is not done atomically, potentially racing with another CPU calling set_tsk_thread_flag().

Replace the non-atomic ORR+STR with an STSET instruction. While STSET requires ARMv8.1 and an assembler that understands LSE atomics, the MTE feature is part of ARMv8.5 and already requires an updated assembler.

commit 176ddd89171ddcf661862d90c5d257877f7326d6 upstream.

When the cache_type for the SCSI device is changed, the SCSI layer issues a MODE_SELECT command. The caching mode details are communicated via a request buffer associated with the SCSI command with data direction set as DMA_TO_DEVICE (scsi_mode_select()). When this command reaches the libata layer, as a part of generic initial setup, libata layer sets up the scatterlist for the command using the SCSI command (ata_scsi_qc_new()). This command is then translated by the libata layer into ATA_CMD_SET_FEATURES (ata_scsi_mode_select_xlat()). The libata layer treats this as a non-data command (ata_mselect_caching()), since it only needs an ATA taskfile to pass the caching on/off information to the device. It does not need the scatterlist that has been setup, so it does not perform dma_map_sg() on the scatterlist (ata_qc_issue()). Unfortunately, when this command reaches the libsas layer (sas_ata_qc_issue()), libsas layer sees it as a non-data command with a scatterlist. It cannot extract the correct DMA length since the scatterlist has not been mapped with dma_map_sg() for a DMA operation. When this partially constructed SAS task reaches pm80xx LLDD, it results in the following warning:

"pm80xx_chip_sata_req 6058: The sg list address start_addr=0x0000000000000000 data_len=0x0end_addr_high=0xffffffff end_addr_low=0xffffffff has crossed 4G boundary"

commit 31166efb1cee348eb6314e9c0095d84cbeb66b9d upstream.

The ixgbe driver currently generates a NULL pointer dereference when performing the ethtool loopback test. This is due to the fact that there isn't a q_vector associated with the test ring when it is setup as interrupts are not normally added to the test rings.

To address this I have added code that will check for a q_vector before returning a napi_id value. If a q_vector is not present it will return a value of 0.

commit ef963ae427aa4669905e0a96b3bd9d44dc85db32 upstream.

A for-loop is using a u8 loop counter that is being compared to a u32 cmp_dcbcfg->numapp to check for the end of the loop. If cmp_dcbcfg->numapp is larger than 255 then the counter j will wrap around to zero and hence an infinite loop occurs. Fix this by making counter j the same type as cmp_dcbcfg->numapp.

commit 7ee3c61dcd28bf6e290e06ad382f13511dc790e9 upstream.

Just like ip/ip6/arptables, the hooks have to be removed, then synchronize_rcu() has to be called to make sure no more packets are being processed before the ruleset data is released.

Place the hook unregistration in the pre_exit hook, then call the new ebtables pre_exit function from there.

Years ago, when first netns support got added for netfilter+ebtables, this used an older (now removed) netfilter hook unregister API, that did a unconditional synchronize_rcu().

Now that all is done with call_rcu, ebtable_{filter,nat,broute} pernet exit handlers may free the ebtable ruleset while packets are still in flight.

This can only happens on module removal, not during netns exit.

The new function expects the table name, not the table struct.

This is because upcoming patch set (targeting -next) will remove all net->xt.{nat,filter,broute}_table instances, this makes it necessary to avoid external references to those member variables.

The existing APIs will be converted, so follow the upcoming scheme of passing name + hook type instead.

commit a714e27ea8bdee2b238748029d31472d0a65b611 upstream.

Commit a14d273ba159 ("net: macb: restore cmp registers on resume path") introduces the restore of CMP registers on resume path. In case the IP doesn't support type 2 screeners (zero on DCFG8 register) the struct macb::rx_fs_list::list is not initialized and thus the list_for_each_entry(item, &bp->rx_fs_list.list, list) loop introduced in commit a14d273ba159 ("net: macb: restore cmp registers on resume path") will access an uninitialized list leading to crash. Thus, initialize the struct macb::rx_fs_list::list without taking into account if the IP supports type 2 screeners or not.

This is because switches from the Topaz family (88E6141 / 88E6341) have the address of the temperature sensor register different from Peridot.

This address is instead compatible with 88E1510 PHYs, as was used for Topaz before the above mentioned commit.

Create a new mapping table between switch family and PHY ID for families which don't have a model number. And define PHY IDs for Topaz and Peridot families.

Create a new PHY ID and a new PHY driver for Topaz's internal PHY. The only difference from Peridot's PHY driver is the HWMON probing method.

Prior this change Topaz's internal PHY is detected by kernel as:

PHY [...] driver [Marvell 88E6390] (irq=63)

And afterwards as:

PHY [...] driver [Marvell 88E6341 Family] (irq=63)

commit 97684f0970f6e112926de631fdd98d9693c7e5c1 upstream.

Currently, tcp_allowed_congestion_control is global and writable; writing to it in any net namespace will leak into all other net namespaces.

tcp_available_congestion_control and tcp_allowed_congestion_control are the only sysctls in ipv4_net_table (the per-netns sysctl table) with a NULL data pointer; their handlers (proc_tcp_available_congestion_control and proc_allowed_congestion_control) have no other way of referencing a struct net. Thus, they operate globally.

Because ipv4_net_table does not use designated initializers, there is no easy way to fix up this one "bad" table entry. However, the data pointer updating logic shouldn't be applied to NULL pointers anyway, so we instead force these entries to be read-only.

These sysctls used to exist in ipv4_table (init-net only), but they were moved to the per-net ipv4_net_table, presumably without realizing that tcp_allowed_congestion_control was writable and thus introduced a leak.

Because the intent of that commit was only to know (i.e. read) "which congestion algorithms are available or allowed", this read-only solution should be sufficient.

The logic added in recent commit 31c4d2f160eb: ("net: Ensure net namespace isolation of sysctls") does not and cannot check for NULL data pointers, because other table entries (e.g. /proc/sys/net/netfilter/nf_log/) have .data=NULL but use other methods (.extra2) to access the struct net.

commit 4e39a072a6a0fc422ba7da5e4336bdc295d70211 upstream.

Fix this panic by adding more rules to calculate the value of @rss_size_max which could be used in allocating the queues when bpf is loaded, which, however, could cause the failure and then trigger the NULL pointer of vsi->rx_rings. Prio to this fix, the machine doesn't care about how many cpus are online and then allocates 256 queues on the machine with 32 cpus online actually.

Once the load of bpf begins, the log will go like this "failed to get tracking for 256 queues for VSI 0 err -12" and this "setup of MAIN VSI failed".

Thus, I attach the key information of the crash-log here.

commit 0775ebc4cf8554bdcd2c212669a0868ab68df5c0 upstream.

__ibmvnic_open calls napi_disable without checking whether NAPI polling has already been disabled or not. This could cause napi_disable being called twice, which could generate deadlock. For example, the first napi_disable will spin until NAPI_STATE_SCHED is cleared by napi_complete_done, then set it again. When napi_disable is called the second time, it will loop infinitely because no dev->poll will be running to clear NAPI_STATE_SCHED.

To prevent above scenario from happening, call ibmvnic_napi_disable() which checks if napi is disabled or not before calling napi_disable.

[ Upstream commit 45c2f70cba3a7eff34574103b2e2b901a5f771aa ]

for_each_mem_range() uses a loop variable, yet looking into code it is not just iteration counter but more complex entity which encodes information about memblock. Thus condition i == 0 looks fragile. Indeed, it broke boot of R-class platforms since it never took i == 0 path (due to i was set to 1). Fix that with restoring original flag check.

Although every Beelink GS1 seems to have external 32768 Hz oscillator, it works only on one from four tested. There are more reports of RTC issues elsewhere, like Armbian forum.

One Beelink GS1 owner read RTC osc status register on Android which shipped with the box. Reported value indicated problems with external oscillator.

In order to fix RTC and related issues (HDMI-CEC and suspend/resume with Crust) on all boards, switch to internal oscillator.

[ Upstream commit 8e53324021645f820a01bf8aa745711c802c8542 ]

Convert vcpu_vmx.exit_reason from a u32 to a union (of size u32). The full VM_EXIT_REASON field is comprised of a 16-bit basic exit reason in bits 15:0, and single-bit modifiers in bits 31:16.

Historically, KVM has only had to worry about handling the "failed VM-Entry" modifier, which could only be set in very specific flows and required dedicated handling. I.e. manually stripping the FAILED_VMENTRY bit was a somewhat viable approach. But even with only a single bit to worry about, KVM has had several bugs related to comparing a basic exit reason against the full exit reason store in vcpu_vmx.

Upcoming Intel features, e.g. SGX, will add new modifier bits that can be set on more or less any VM-Exit, as opposed to the significantly more restricted FAILED_VMENTRY, i.e. correctly handling everything in one-off flows isn't scalable. Tracking exit reason in a union forces code to explicitly choose between consuming the full exit reason and the basic exit, and is a convenient way to document and access the modifiers.

No functional change intended.

gcc-11 adds support for -fsanitize=kernel-hwaddress, so it becomes possible to enable CONFIG_KASAN_SW_TAGS.

Unfortunately this fails to build at the moment, because the corresponding command line arguments use llvm specific syntax.

Change it to use the cc-param macro instead, which works on both clang and gcc.

So far we don't increase the max read request size if we switch to jumbo mode before bringing up the interface for the first time. Let's change this.

[ Upstream commit 24c109bb1537c12c02aeed2d51a347b4d6a9b76e ]

The mixed signed bounds check really belongs into retrieve_ptr_limit() instead of outside of it in adjust_ptr_min_max_vals(). The reason is that this check is not tied to PTR_TO_MAP_VALUE only, but to all pointer types that we handle in retrieve_ptr_limit() and given errors from the latter propagate back to adjust_ptr_min_max_vals() and lead to rejection of the program, it's a better place to reside to avoid anything slipping through for future types. The reason why we must reject such off_reg is that we otherwise would not be able to derive a mask, see details in 9d7eceede769 ("bpf: restrict unknown scalars of mixed signed bounds for unprivileged").

commit d2f7eca60b29006285d57c7035539e33300e89e5 upstream.

Since uprobes is not supported for thumb, check that the thumb bit is not set when matching the uprobes instruction hooks.

The Arm UDF instructions used for uprobes triggering (UPROBE_SWBP_ARM_INSN and UPROBE_SS_ARM_INSN) coincidentally share the same encoding as a pair of unallocated 32-bit thumb instructions (not UDF) when the condition code is 0b1111 (0xf). This in effect makes it possible to trigger the uprobes functionality from thumb, and at that using two unallocated instructions which are not permanently undefined.
